Hello,

I recently installed julia (Version 0.6.0-dev.1393 (2016-12-09 01:03 UTC)/ Commit e19a8bf (164 days old master)/x86\_64-linux-gnu) on my Ubuntu 16.04 machine.  
I am getting various errors after installing the packages Mamba and Jags; and module DataArrays.  
I need the packages to run Bayesian structural equation modeling, which I currently run in R. I am hoping that I can improve the speed of the computation by switching to Julia.  
I already have JAGS 4.1.0 installed on my machine and the binary can be found in /usr/local/bin/jags. Is this okay? in the installation manual I read " This version of the Jags.jl package assumes that Jags is installed and the jags binary is on $PATH. The variable JAGS\_HOME is currently initialized either from ~/.juliarc.jl or from an environment variable JAGS\_HOME. JAGS\_HOME currently only used in runtests.jl to disable attempting to run tests that need the Jags executable on $PATH." However, I am not sure how I can test the $PATH.

I can install the packages (e.g. Pkg.add("Mamba), but there are some underlying errors. For example, while testing with Pkg.test(“Mamba”) I get “extra token “NAtype” after end of expression” and other errors, which I am not sure how to addrees. I include the full message below.

Could you please help me with this? I tried to run a search online but couldn’t find an answer. I might have missed something basic but I am new to the use of Julia.

Thanks in advance for any help,

Michela

The first thing you should try is upgrading to the latest release candidate. See [this topic](https://discourse.julialang.org/t/julia-0-5-2-release-and-0-6-0-release-candidate-1-available/3630). FWIW, using this version `DataArrays.jl` loads on my machine using the latest RC and released packages, and tests run correctly.

Wherever you installed a 6 month old nightly master build from should not be used. Install a stable release from the generic linux binaries.
